MAOHINE FOR GAPPING MULTISIDED PAPER BOTTLES.

Specification of Letters Patent.

Application filed November 15, 1917. Serial No. 202,177.

To all whom it may concern Be it known that I, IJEQNARD DEE STEPH-ENSQN,a citizen of the United States, and resident of the borough ofManhattan, in the city and State of New York, have invented a new anduseful Improvement in Machines for Capping Multisided Paper Bottles, ofwhich the following is aspecification.

The object of my invention is to provide a machine for applying metalcaps to multisicled paper bottles, and is particularly directed tomachines for applying the top caps to said multi-sided paper bottles.

My invention comprises certain improvements in machines for cappingmulti-sided paper bottles, in which the top sides of the paper bottleand the inner uprising walls of the metal cap are first flared by theaction ofa plunger and then the outer depending walls of the metal capare forced inwardly V by theaction of crimping jaws to pinch the topsides of the bottle snugly between the inner and outer walls of themetal cap, the inclination of the said top sides of the bottle and theinner and outer walls of the cap serving to securely look the capto thebottle.

A further object is to provide very simple and effective means foraccomplishing the above result.

A practical embodiment of my invention is represented in theaccompanying drawin s, in which,

igure 1 represents the bottle capping machine in front elevation,certain of the parts being broken away.

Fig. 2 is a side elevation of the machine.

Fig. 3 is a section taken in the plane of the line III-III of Fig. 2,looking in the direction of the arrow.

Fi 4 is a section taken in the plane of the line IVIV of Fig. 2, lookingin the direction of the arrow.

Fig. 5 is a considerably enlarged detail section at the top of themachine, showing the parts in the position which they assume with theplunger raised and the crimping jaws open, and

Fig. 6 is a similar view with the parts shown in dotted lines in theposition which they assume with the plunger lowered and the crimpingjaws open and in full lines in the position they assume with the plungerlowered and the crimping jaws closed.

The present invention is directed particularly to the capping of the topof the paper bottle, a co-pending application being directed to meansfor capping the bottom of the bottle.

The paper bottle 1, illustrated herein, to be capped, is shown oftapered rectangular form with its bottom cap 2 already applied.

he top metal cap 3 has uprising inner side walls 4 and depending sidewalls 5. This cap is placed on the top of the bottle with the top sidesof the bottle located between the inner and outer side walls of the cap.

The base 6 of the capping machine is provided with an upright 7 havingan overhanging arm 8. vertical plunger 9 is slidably mounted in theover-hanging arm 8 of the upright, the head at the bottom of the plungerhaving tapered sides 10 arranged, when the plunger is lowered, to enterthe cap 3 and force its inner side walls 4 outwardly and at the sametime force the top sides of the bottle 1 outwardly. This plunger has adouble pin and slot connection 11, 12, with the overhanging arm 8 of theupright 7. The lower'end of the plunger is provided with pairs of cars13, 14:, spaced apart, the pairs of ears corresponding in number to thesides of the bottle to be capped. Between each pair of ears, I pivot acrimping jaw 15 at 16, which jaw is provided with a tapered uprising arm17 and with a laterally extended crimping face 18. This crimping face isarranged to be brought toward and away from its corresponding taperedside 10 of the head of the plunger as the jaw is rocked. A spring 19serves to open the jaws by swinging the uprising arm 17 inwardly towardthe plunger 9.

The means for controlling the movement of the plunger and the movementsof the crimping jaws is constructed, arranged and operated as follows:

A wedge block 20 is slidably mounted on the plunger 9, and it isprovided with wedges 21 corresponding in number to the crimping jaws,the narrow ends of which wedges are interposed between the upper ends ofthe arms 17 of the jaws and the plunger. A pin 22 carried by the plunger9, rests upon the top of the wedge block 20, when the block and plungerare in their raised position.

A lever 23 is pivoted at 24 to the overhanging arm 8 of the machine upriht, the free end of which lever is connected to the upper end of avertically sliding rod 25 which passes downwardly through the upright 7to some suitable operating means, not shown herein, for raising andlowering the rod. The lever 23, intermediate its ends, is connected tothe wedge block 20 by links 26.

A holder 27 is provided on the upright 7 for holding the bottle inposition on the base 6, with the top of the bottle directly beneath thehead of the vertically sliding plunger 9.

In operation, the positions shown in the multi=sided paper bottle lacedin position beneath the plunger, an the metal cap placed in position onthe top of the bottle. The lever 23 is rocked downwardly. The first partof the downward movement of the lever 23 is accompanied by the downwardmovement of the plunger 9 and wedge block 20 together. This simultaneousdownassume the parts to be in Figs. 1 and 2, with ward movement of theplunger and wedge block continues until the head of the wedge blockenters and seats within the metal cap 3, this movement serving to flarethe inner side walls of the cap and the top sides of the bottleoutwardly. To prevent undue endwise strain on the bottle, the downwardmovement of the plunger is limited by its pin and slot connection 11,12, with the overhanging arm 8 of the upright. The further downwardmovement of the lever 23 will cause the wedge block 20 to be forceddownwardly along the plunger, thus swinging the arms 17 of the crimpingjaws downwardly to close the jaws. This closure of the jaws will forcethe outer side walls 5 ot the. metal cap inwardly into snug engagementwith the top sides of the bottle and crimp the same into a permanentlocking position. The lever 23 may thenbe swung upwardly. The firstportion of this upper movement will withdraw the wedge block 20 from itsengagement with the arms of the jaws, permitting the jaws to open underthe influence of the springs 19. The further upward movement of thelever 23 will cause the wedge block 20 to raise the plunger 9, throughthe medium of the pin 22, sufficiently to permit the removal of thecapped bottle.

It is to be understood that this machine is applicable for cappingbottles of many different sides.

It is evident that various changes may be resorted. to in the form,construction and arrangement of the several parts without departing fromthe spirit and scope of my invention, and hence I do not wish to limitinyself to the construction herein described, mt

\Vhat I claim is:

In a machine for securing metal caps to multiesided paper bottles, asuitable support, a plunger movable therein. and having a tapered headfor flaring the, inner cap walls and the top sides of the bottle,crimping jaws carried by the plun er tor clamping the top sides of thebott e between the inner and outer cap walls, and means for controllingthe operation of the plunger and crimping jaws comprising a wedge blockhaving a lost motion connection with the plunger and wedge blockoperating means.

In testimony, that I claim the foregoing as my invention, I have signedmy name this 31st day of October 191 LEONARD DEE STEPHENSON.
